Dahlia plant named ‘Golia Dbyel’

ABSTRACT

A new  Dahlia  plant named ‘Golia Dbyel,’ particularly distinguished by the large medium yellow ‘collerette’ type flowers, full and compact plant habit with excellent branching, medium green foliage, and good floriferiousness.

Latin name of the genus and species of the plant claimed: Dahlia hybrid.

Varietal denomination: ‘Golia Dbyel’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Dahlia, botanically known asDahlia hybrid and hereinafter referred to by the variety name ‘GoliaDbyel.’

‘Golia Dbyel’ is a product of a planned breeding program. The newcultivar ‘Golia Dbyel’ has large medium yellow ‘collerette’ typeflowers, full and compact plant habit with excellent branching, mediumgreen foliage, and good floriferiousness.

‘Golia Dbyel’ originates from a sibling cross hybridization in acontrolled breeding program in Andijk, Netherlands. The pollination tookplace in August 2006 and the seed sown in November 2006. ‘Golia Dbyel’was selected as one flowering plant within the progeny of the statedcross in February 2007 in a controlled environment in Andijk,Netherlands.

The female parent was an unpatented, proprietary hybrid seedlingidentified as ‘D05-115-4,’ a scarlet and yellow flower, with betterquality flowers, fuller plant habit with better vigor.

The male parent of ‘Golia Dbyel’ was an unpatented, proprietary hybridseedling identified as ‘D05-115-5,’ a scarlet and yellow flower, with asmaller flower size, and larger plant size.

The first act of asexual reproduction of ‘Golia Dbyel’ was accomplishedwhen vegetative cuttings were propagated from the initial selection inFebruary 2007 in a controlled environment in Andijk, Netherlands.

Horticultural examination of plants grown from cuttings of the plantinitiated in February 2007 in Andijk, Netherlands, and continuingthereafter, has demonstrated that the combination of characteristics asherein disclosed for ‘Golia Dbyel’ are firmly fixed and are retainedthrough successive generations of asexual reproduction.

‘Golia Dbyel’ has not been observed under all possible environmentalconditions. The phenotype may vary significantly with variations inenvironment such as temperature, light intensity and day length.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawings show typical flower and foliagecharacteristics of ‘Golia Dbyel’ with colors being as true as possiblewith an illustration of this type. The photographic drawings show inFIG. 1, a flowering potted plant of the new variety and in FIG. 2, aclose-up of the flowers.

DETAILED BOTANICAL DESCRIPTION

The plant descriptions and measurements were taken in Hillscheid,Germany, in mid-May 2009 on plants that were growing in 12 cm pots onbenches in a greenhouse trial, and were about 14 weeks old. Theaforementioned whole plant photograph was taken in June 2009, and theflower close-up was taken in April 2009, both in Hillschied, Germany.The plants were growing in bench trials in a greenhouse and were about12 weeks of age.

Color references are made to The Royal Horticultural Society ColourChart (R.H.S.) 2001.

BRIEF SUMMARY OF INVENTION

The following traits have been repeatedly observed and are determined tobe basic characteristics of the new variety. The combination of thesecharacteristics distinguishes this Dahlia as a new and distinct variety.
